### Understanding Simple Diode Circuits #### Figure 16-1 The diagrams (a), (b), and (c) in Figure 16-1 depict simple electrical circuits containing resistors, diodes, and voltage sources. Each subfigure demonstrates a different circuit configuration. 1. **Subfigure (a)** - **Components:** - Resistor (\( R_1 \) = 500 Ω) - Voltage Source (20 V) - Diode - **Description:** - The circuit consists of a 20 V voltage source in series with a 500 Ω resistor and a diode. 2. **Subfigure (b)** - **Components:** - Resistor (\( R_1 \) = 500 Ω) - Voltage Source (1 V) - Diode - **Description:** - The circuit is similar to (a), with a 1 V voltage source instead of 20 V. The 1 V voltage source is in series with a 500 Ω resistor and a diode. 3. **Subfigure (c)** - **Components:** - Resistor (\( R_1 \) = 1 kΩ) - Voltage Source (50 V) - Diode - Resistor (\( R_2 \) = 1 kΩ) - Node B - **Description:** - This circuit has a 50 V voltage source in series with a 1 kΩ resistor and a diode. Additionally, there is a parallel connection that includes another 1 kΩ resistor and the diode. #### Question **What is the current through \( R_1 \) in Figure 16-1(c) if the diode is silicon?** 1. 49.7 mA 2. 49.3 mA 3. 0 A 4. 25 mA **Answering the Question:** To determine the current through \( R_1 \), we need to consider the characteristics of a silicon diode. Typically, a silicon diode requires approximately 0.7 V to turn on and conduct current. By calculating the voltage drop across the resistor and the diode, and subsequently using Ohm's Law, we can find the current flowing through \( R_1 \). **Note:** For detailed analysis and calculations, students are encouraged to refer to theoretical and practical
